So?Have you tried swapping coils to see if the problem cylinder moves?
Who says your wiring is all good?
I would be checking that before messing with the injectors. But it's your call. Up until now this site has wasted your money.
To me the only way to ensure you are getting genuine anything is buy from a reputable source.
I seriously doubt the coils you bought are genuine. There are fakes going around.
I'm glad they seem to be working for you.
Exactly.
More than likely one muffler swap would solve all your worries.
Unless too much money is a worry, in which case a titanium exhaust will fix that.
